Prematurely retiring from professional cricket due to injury in 2008, at the age of only 31, he became an author and journalist and in 2013 he joined the BBC's Test Match Special as a commentator for The Ashes series against Australia. He replaced James Whitaker as England's chief national cricket selector in 2018.[1]

During thirteen seasons of first-class cricket, he scored 34 centuries. He hit a peak in 2003, scoring 135, 0, 122, 149, 113, 203, 36, 108 and 32 for Kent in July of that year. He averaged 72.99 for the 2003 first-class season when he was selected for England.

He left his native county following the 2004 season and joined Middlesex for 2005. He captained the county for two seasons during 2007 and 2008. After missing most of the 2008 season due to an ankle injury, Smith announced his retirement later that year.[5]
